Key Findings

  • 01The digital impression procedure has an average carbon footprint of approximately 550 g CO2-eq.
  • 02The analog impression procedure has an average carbon footprint of approximately 1620 g CO2-eq.
  • 03The digital method's carbon footprint is nearly threefold lower than the analog method.
  • 04The analog method's higher impact is due to disposable materials and waste requiring incineration.
  • 05The digital method's environmental benefit is contingent on high clinical utilization of the intraoral scanner.

Application

Design takeaway

Prioritize digital impression technologies in dental design projects to minimize disposable material consumption and associated waste, thereby reducing the overall carbon footprint of dental procedures.

How to apply

When designing or specifying dental equipment and workflows, conduct a comparative environmental impact assessment, favoring digital solutions that demonstrably reduce waste and emissions, and ensure the design supports high utilization rates.

Project actions

  • 01When researching materials, consider their entire lifecycle impact, not just their initial cost or performance.
  • 02Quantify the environmental benefits of your design choices using metrics like carbon footprint or waste reduction.

Method & Evidence

AimTo quantify and compare the Global Warming Potential of conventional analog and digital impression techniques for single-tooth crown manufacturing in a dental practice.
MethodLife Cycle Assessment (LCA)
ProcedureA cradle-to-grave LCA was performed, defining a positive dental model as the functional unit. The assessment focused on material consumption, waste streams, and equipment usage, excluding patient travel and facility energy.
ContextDental practice, Germany

Variables

IVImpression technique (analog vs. digital)
DVGlobal Warming Potential (carbon footprint)
CVFunctional unit (positive dental model), exclusion of patient travel and facility energy, regional context (Germany)

Strengths & Limitations

Strengths

  • +Quantifies environmental impact using a recognized methodology (LCA).
  • +Direct comparison between two common dental procedures.

Limitations

The study's findings are context-specific to Germany's waste management and energy systems, so direct comparisons to other regions require careful consideration.

Reliability & validity

The study's validity is strengthened by its use of a standardized LCA methodology. Reliability could be enhanced by replicating the study in different geographical contexts with varying energy and waste infrastructures.

Think critically

How might the 'cradle-to-grave' assessment change if the manufacturing of the intraoral scanner itself, including its energy consumption and material sourcing, were more heavily weighted or if the lifespan of the scanner was significantly shorter?

05

Design Principles

"Minimize material waste and energy consumption through process digitization and efficient resource utilization."

As the healthcare sector faces increasing scrutiny for its environmental footprint, design choices in dental practices can lead to substantial reductions in greenhouse gas emissions. This research provides a quantifiable basis for prioritizing sustainable material and process choices in dental design projects.

06

What This Means for Your Design

Using digital scanners instead of traditional putty for dental impressions is much better for the environment because it creates less trash and uses fewer disposable items.

How to use in your project

  • 1.Use this study to justify the selection of a digital design process over a traditional one, citing the reduced environmental impact as a key benefit.
